Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724516, here are decompositions:

5 + 8724511 = 8724516
19 + 8724497 = 8724516
23 + 8724493 = 8724516
29 + 8724487 = 8724516
37 + 8724479 = 8724516
79 + 8724437 = 8724516
139 + 8724377 = 8724516
193 + 8724323 = 8724516

Showing the first eight; more decompositions exist.
